Can we use 800 IOs with Modicon M580 Safety System without impact TUV certification


There is no issue to use 800 series IOs without any impact on TÜV certificate on a M580 Safety configuration.
As a general rule, all of Remote Distributed equipments on Ethernet allowed in M580 system could be considered as “non-interfering”
for Safety M580 modules. However, of course, 800 series IOs data are not supposed to be used to perform safety functions.
